  1. 2005-2010 Mustang GT Tech
    Hi guys, I'm back again, with more problems... So this time, after I got new tires and rims, my mileage seems to be a little bit off. I used to have the stock 2010 GT 245/45R19 and right now I have 255/35R20 in the front and 275/35R20 in the rear. I calculated that the revs per mile is...
  2. 2011 - 2014 Mustang GT Tech
    My 2014 5.0 is at the dealership being serviced right now because I needed a new window motor for the passenger side. Anyway, I asked them if they could check if the ECU has been flashed because I bought the car used and would like to know. He said that they can't find out and that there's no...
  3. Mustang S550 General Discussion
    So I have been thinking about the mods I would like to do to my 17 5.0 but I'm worried about doing anything that could possibly ruin the warranty. I emailed the assistant manager in service at my dealership and he basically said that any modifications will not necessarily void the warranty...
  4. 2005-2010 Mustang Talk
    I have a 2007 V6 Mustang with only an aftermarket muffler and a K & N filter. I was looking to eventually drop money on some long tube headers, throttle body, and eventually a full exhaust system. Unfortunately, I have no idea how tuners work and was stuck whether or not a tuner can only be used...
  5. 2005-2010 Mustang GT Tech
    Hey folks, I have a GT 2006 4.6L V8 which is currently throwing P0171 and P0174 error codes meaning system too lean on banks 1 and 2. It also failed its MOT on emissions (CO2, I believe) despite passing fine last year. The LTFT 1 & 2 are maxing out at 25% under throttle load which is throwing...
  6. 2005-2010 V6 Mustang Tech
    Good afternoon, everyone! I think I've messed up my car during a tune and I'm unsure what to do at this point. Backstory: 2007 V6 130,000K miles. I've had a tune and CAI on the car for 8 years now. The most recent tune change was from a 93 Octane Firm Shift JLT to a 91 Octane Performance...
  7. 2015+ 5.0 Tech
    Bought a 2017 base model GT about 6 weeks ago. Had hoped my truck would make it another year and would have bought the GT Premium, but you can't always get what you want. Anyway, I'm not planning any mods. I run 93 octane most of the time, but occasionally 91. Is it worth my money to get a...

  9. V6 Talk
    I'm sixteen and I have an excellent opportunity to buy a 2004 Mustang V6 for much cheaper than market value. I haven't even seen a picture of it but I want to be prepared in case I have to jump on this chance. That, of course, requires some questions. 1. Is the V6 even worth it? I've grown up...
  10. 2011 - 2014 Mustang GT Tech
    Hi guys, I've just installed a 2014 engine into my 2011 GT and I think my ECU has a tune on it, only worked it out when it would only run with a big JLT intake and wont run with a stock one. I want to retune the ECU to a tune that I know and trust. Now with that, can I just flash the ECU...
  11. 2011 - 2014 Mustang GT Tech
    Hi guys, I am in the UK and have a 2011 Mustang GT. I've just installed a late 2014 crate engine (guessing late 14 by the different dipstick) into it as the last one died. However, we cant get the crank sensors to relearn and we've tried everything, revving it higher, taking it for a drive...
  12. 2005-2010 V6 Mustang Tech
    Hey guys. A little background: I currently drive a 2007 Mustang V6, which I've had since 2009. The CAI / tune in question has been on the car since 2012-2013. Awhile back I had my car in the shop getting a fan replaced. No big deal, and I informed them that the car had a custom tune and not...
  13. 4.6L Tech
    My Mustang has been idling very inconsistently now that the weather is getting colder. After the car warms up, the idle will be from 500ish to 800ish and bounce in between those throughout the entire drive. When coasting in neutral it sometimes will hover at 800 or so consistently, but usually...
  14. 4.6L Tech
    Okay, so I have an 04 GT with the basic mods (CAI, TB, plenum, X-pipe w/ high flow cats, MAC catback, and 3.73's) I've noticed this for a while, but haven't really cared much to try to find a solution. No better time than the present, right? Basically, when the engine is still cold and I try to...

    Anyone know much about this? What affect it has on your car in terms of performance and wear?
  16. Mustang S550 (2015+ Mustangs)
    Any one with experience with Steeda Tune on a 2016 GT Automatic? I'm currently running a Lund tune and it has issues. I've listed the likes and dislikes below. Please comment regarding Speeda Tune on any of these areas mentioned below. Need to mention that the Lund tune is supposedly based off...

    Sorry, not sure how to edit the title as I've misspelled Steeda in the title and can't edit my tags for some reason. I've started a new thread with the correct title and everything else.
  18. 2011 - 2014 Mustang GT Tech
    Hi guys, i know this topic has been discussed before, but i don't seem to quite find the answer i'm looking for. I have a 2013 5.0, i'm currently using the diablosport intune i1000, and running the 91 octane canned tune, since there's nowhere in the country to find 93 octane fuel. However, a...
  19. 4.6L Tech
    So I'm in the transition of converting my stang to drag only and I'm doing weight reduction. I removed the airbags and installed airbag delete's. I have a X3 tuner from AM's bama team. I had just assumed that they could write a tune for me the would clear any codes that would come up and turn...
  20. 2005-2010 Mustang GT Tech
    Just got my 2009 GT dyno tuned by Dave Guy at DGR Performance, and WOW I am pleased! I was having many issues with my Mustang's idle after installing Hot Rod Cams: Idle surging, Low RPM chugging, and Difficulty getting going in first gear and reverse. Dave did a great job correcting for these...
